Allroad 2002 2.5TDI Quattro AUTO TRANSMISSION Question

[ametlib]

Hi.
Didn't take the time to read the whole thread but if you have not changed the transmission oil yet , I suggest you start there. The fault you describe sounds like the converter lock up is not beeing activated and I,ve seen this and similar faults beeing cured by
changing oil and filter

[abby1]

transmission control module is under carpet drivers side

[Tel2]

Thanks, but is that on the drivers side for a left hand drive car or a right hand drive car?

[ametlib]

It's on the cars right side. Generally speaking the two most common faults on 5HP19 is Atf and filter needs to be changed and engine MAF. . . after that - torque converter faulty . .

Thanks for that. I'll work on the fluid and filter. I have already eliminated the MAF.

I did not like my adaptive gear change which revved the engine to high for my liking so I turned it off with ross tech. This did stop it revving so high.

Mine seemed to slip into third when I first got it bur I put up with it. Eventually it spay it's oil out at the same time as blowing the gearbox oil pump. I got that swapped out and changed the oil and filter with genuine stuff and it has helped. The oil had been changed according to the service history so I don't think they used the correct oil.

The change into 5th under load became really clunky after that . I put up with and it has got better. I did find a lot of info on the gearbox on some Russian audi sites as they rebuild them. They pointed towards solenoid problems. Maybe worth a Google to see if they throw any light on the problem.

For those who don't know. 9litres of oil is the total capacity of the gearbox. Only 5 comes out as the rest remains in the box. Without stripping the box there is no way of getting it out.
When topping up the car needs to be running and the oil temp at 40 degrees using ross tech. There is a large plug under the gearbox sump that you pump oil into until it starts coming out of the plug hole.

The carpet not being wet does not rule out water in the yfootwell as the carpet is about 2 inches taller than it seems. The seats are easy to remove so pull it out and be sure no water is in the footwell.

Hope this helps in some way

Hi Mike Ryan
I have done most of the oil.and filter this made a difference but still had this 1st gear lockout . Last event was a battery change and this had made a big diff. When removed from car after running for 30 min a starting ok i took it off and had it checked ....Shot 12 1 v so that equates to 20% charge. It should have been 12.7 to13 v for 100% charge. Since battery changed i have not had a gearlock out at all. Charge rate is 14.2 v so hoping low v on startup has been messing with ecu��������

Mike Ryan You're right ,This program called DSP (dinamic shift program) In the TCU. Under certain conditions, the DSP can cause draw gears to hi rev. This program records the driving characteristics in memory (log) And adjusts the behavior of the transmission accordance the log. If you disconnect the car battery For a while This LOG Is deleted Then the transmission behavior chang.

I have a somewhat similar problem which I have been unable to match anywhere. I even took it to an auto trans specialist this week who is also baffled!

The problem almost only occurs when the vehicle is cold. After a few miles it goes away. The are times when it refuses to change from 1st to 2nd automatically. You can get to 30mph and it still won't change. As soon as you flip it to manual mode you can change it with no problems. It also has the same delays between the gears mentioned by bigandy82. This usually only applies to the lower gears and it will rev between gears. Again this tends to disappear as the vehicle warms up.

There are no warning lights. All the gear lights on the dashboard are displayed correctly. Once the code 01119 came up (transmission shift-range gear position signal). After deleting the code it has never come back.

The auto trans specialist originally thought it was going to be the "switch" from my description but after test driving it 3 times from cold he is convinced it is not as all the lights are correct and there are no fault codes. His guess is that it is the gearbox ecu but he does not deal with them! That is an expensive item to buy and non trivial to get at under the driver's seat so I am looking for anyone who has come across a similar problem and can confirm the correct resolution.

The gearbox is a ZF5HP19 on an Allroad 2.5TDi 2005 C5

Thanks for all and any help.

Hi Tel2,

Did you get to the bottom of this & was it rectified?
I have almost exactly the same issue & symptoms, part from I can get it to go away in Sport mode only & it only started when we had the snow the other week

[Tel2]

Unfortunately not, no-one could identify the problem. Everyone kept suggesting different possible fixes all of which were expensive with no guarantee they would resolve the problem. The vehicle continued like this for several months and then I completely lost gears 4 & 5. The prognosis this time was a gearbox rebuild which was going to work out at £3,000 total so I scrapped the car.
